If x = f(t), y = g(t), where t is a parameter, then
CALCULATION:
Given: x = a sec θ and y = b tan θ
Here, we have to find
So, first we have to find dx/dθ and dy/dθ
As we know that,
⇒ dx/dθ = a sec θ ⋅ tan θ------(1)
As we know that,
⇒ dy/dθ = b sec2 θ-----------(2)
From (1) and (2), we can say that,
Hence, correct option is 3.
